Abstract
To provide a circuit board in which a curvature of a display surface can be controlled, or to provide a highly portable circuit board. A circuit board includes a substrate with flexibility and a curvature control mechanism. The curvature control mechanism includes a first electromagnet and a second electromagnet provided over a first surface of the substrate, an insulating film provided over the first and second electromagnets, and wirings electrically connected to the first and second electromagnets.

A display system comprising:
- a display device comprising:
- a display portion;
- and
- a curvature control mechanism comprising a plurality of electromagnets provided along an end of the display portion, the plurality of electromagnets comprising a first electromagnet, a second electromagnet, and a third electromagnet;
- a distance data detection sensor configured to detect a distance data between a user and the distance data detection sensor;
- and
- a curvature control circuit configured to control a curvature of the display device on a basis of the distance data by controlling operation of the curvature control mechanism,
- wherein:
- the first electromagnet and the second electromagnet are in a first row and are directly adjacent to each other,
- a first axis passes through a midpoint of the first electromagnet and a midpoint of the second electromagnet,
- the first electromagnet is electrically connected to a first wiring,
- the second electromagnet is electrically connected to a second wiring that is different from the first wiring so that a direction of current flowing in the second electromagnet is able to be changed independently of the first electromagnet,
- the third electromagnet is in a second row,
- a center axis of the third electromagnet passes through a midpoint of a distance between the first electromagnet and the second electromagnet, and
- the center axis is orthogonal to the first axis.
